My GE PVM1870SM1SS microwave is dead won't power on at all. I measured the line voltage at the outlet it is 120.4 volts just like the rest of the house. What is the cause of this complete failure. Was using it fine up to two days ago.
Before occured this problem;
First failure--- Two days ago, when I opened the door of the microwave in order to warm
my lunch , LED of the operation panel was shut off.
Then, Power came back after minute. Displayed on the control panel
as "SET CLOCK".
Second Failure---Yesterday, When I used a microwave oven, it had shut off the
power suddenly. The control panel became dark again.
Then, Power came back after minute. Displayed on the control panel
as "SET CLOCK".
Third Failure---This morning, When I push "1" to start EXPRESS COCK, it had
shut off the power suddenly. The control panel became dark again.
I waited power for a while. But no power came back any more.
